They needed people to check a bag, they did check my bag and I had to wait 10 minutes after the flight to get it it wasn’t too bad

They needed people to check a bag, they did check my bag and I had to wait 10 minutes after the flight to get it it wasn’t too bad

We arrived early and finally made it to our gate almost an hour after.

We were delayed 3x and because I didn’t purchase my tickets directly from United Airlines I was told I Have to take care of it myself so I called Underpricer and they helped me but before I changed my flights I took the risk of sticking by what my tickets were and was lucky to have gotten on the original all flight with only 15 mins before take off. not sure if I will do this again

The flight was delayed so the people from a late connecting flight was able to still make the connection.

Everything good until we waited for jet bridge at SFO. Then pilot gets on speaker & said it won’t reach plane- too short, need to go to different gate. Then 5 min later, adjusted plane/jetbridge & all ok?!?

Was a pain having to leave the plane and reboard but glad the plane was fixed

We had to wait almost an hour for the wheelchair porter to be ready to pick up my mother. And when she arrived in Newark airport the porter was not there and she started walking with her cane and her poor mobility. When the Newark porter found her they didn't want to transfer her bags to the wheelchair for her.

My experience was medium staff where great I dislike flying in triple 7 seats very uncomfortable and no room on jet all the rest of the flights where great

Great onboard crew. Boarding was a zoo, I got in line before pre boarding in Group 2, still had my bag force checked. WiFi was glitchy all flight. Seat and bathroom are both tiny unless you pay $$$ for first class.

Staff was generally seeming stressed out and was a bit rude and slow. Plane left late. Pilot was very well-spoken.

Single flights to Cancun purchased through third-party, initially had issues printing luggage labels with the lady at the airport Pearson… Was super friendly and assisted quickly despite being very busy

Very old planes. Seats were not comfortable. Air was not on during the flight leading to incredibly stuffy conditions.

It was so bad experience they wanted just charged passengers for any reason.

Traveling on two legs the food was identical and not very good

The flight was on time and shorter time arrival than planned. I was an ultra basic passenger and understood one personal item on the plane. The announcements of one personal item and zone 9 boarding certainly felt like we were separated from the rest. Actually zone 9 passengers should be boarded second; we are not blocking aisles and can be seated much faster and deboarded faster too.

Still sitting in a hotel when I'm due for work

Delays happen but communication and care were very low on what ended up being a long day.

Terrible experience at the gate. Charged for carry on luggage despite them meeting the requirements for sizing.

Never been on a long haul flight that didn't have on flight entertainment. I hope the way back is better !

Seat barely reclined. Boarding took forever. Flight attendants were not very friendly

The speakers were way too loud. Music was played during boarding too. This noise could've been avoided.

The flight was delayed for 4 hours and the airplane was really old cuz not one thing was working.

Nice crew - very small plane and uncomfortable, with no entertainment options…

The TSA people or whatever you call them were a bit rude- I asked why I had to take my shoes off bc I'm 75 and in the USA, I don't have to. The man didn't need to snap at me. It wasn't even busy! The plane was ok, a bit small for such a long flight, but I'm very familiar with the 737 used ( I fly it often between SFO and SAN) service was ok-nothing special. If I drank alcohol I guess I would be happy with free choices. the plane was HOT and even the FA commented on it. They tried to get it cooler, but it never happened.

Multiple change of the gates at Pearson, delayed flight was extremely uncomfortable.

Never made this leg of the flight since we rebooked through United instead. Did not make it to immigration/US custom due to the delay. Had to spend the night on our own dime in Toronto

YYZ air Canada security messed up which led to my kids missing their flight and having to go on a separate flight later in the day without the rest of the family. Customer service was horrible and have no sense of urgency or compassion for their customers. They refuse to compensate for their errors and making my kids wait hours in the airport. This isn’t the first time we have had issues with this airline and I won’t be flying with them again.

Cancelled flight had to fight for a hotel voucher and lost my upgrade. Not great business.

Flight attendants were delightful, smiling, anticipating needs, and overall excellent. Pilots kept us informed and made 1 of the best soft landings!

Delayed flight and did not do a good job updating us. Entertainment selection was weak, but I was thankful to have the behind the seat screen. No interaction with crew.
